OEM manufacturer Mini Lobe Pump - Sanitary Cam Rotor Pump QZ-Z – Qiangzhong

Product Parameters

Flow calculation Sanitary rotor pump flow 1 .Theoretical flow
The theoretical flow refers to the volume of the medium delivered in a unit of time during the working process of the sanitary rotor pump without considering the loss of leakage, which is:
Theoretical flow = displacement X speed X time 2. Actual flow
The actual flow rate means that the sanitary rotor pump takes into account the leakage loss during the working process, that is, the volumetric efficiency. The general volumetric efficiency is between 80% and 90%.
Actual flow = theoretical flow X volumetric efficiency

Product Structure

Butterfly Rotor Pump:
Thanks to the butterfly rotor, it has certain advantages in conveying high-viscosity materials and materials containing larger particles, and can effectively transport particularly viscous materials.
Single Butterfly Curved Rotor Pump:
The pump is specially designed for the transport of large particles containing materials. Its unique shape and curved form make it an unparalleled superiority to other pumps when transporting large particulate materials. It can effectively avoid particle breakage during the process of conveying materials, and is the preferred pump for conveying granular materials.

Transmission Section Selection:
•Motor + Fixed Ratio Reducer: this method of transmission is simple, the rotor speed is constant, which also determines the flow rate is not adjustable.
•Motor + Mechanical Friction Type Stepless Transmission: this type of transmission is manually adjusted to achieve variable speed. It is characterized by safe and reliable, large torque, flow adjustable stepless. Disadvantages are non-automatic adjustment and more troublesome. The speed must be adjusted in the working process, and it must not be adjusted under stop state. Please refer to the manufacturer’s instructions for use and maintenance specifications.
•Converter Motor + Converter: the speed can be automatically adjusted in this way, which means that the flow can be adjusted steplessly. The advantage is that the degree of automation is high and the low speed torque is large; the disadvantage is that the price of the inverter is relatively high. Please refer to the manufacturer’s instruction manual for maintenance specifications.

Working Principle

The rotor pump has two synchronously reversed rotors (2-4 teeth).
When they rotate, there is suction (vacuum) generated at the inlet to suck in the material to be transported.
The two rotors divide the rotor chamber into several small pieces.
In the space, they operate in the order a →b  →c →d.
When operating to position a, only chamber I is filled with media;
At location b, part of the medium is enclosed in room B;
At position c, the medium is also enclosed in chamber A;
At position d, Room B and Room A communicates with Chamber II, and the media is conveyed to the discharge port.
In this way, the medium (material) is continuously sent out.

This cam lobe pump is a multi-purpose transfer pump which adopts two-lobe, tri-lobe, butterfly or multilobe rotor. As a sanitary volumetric delivery pump, it has the characteristics of low speed, high output torque, high temperature resistance, corrosion resistance, etc. Its unique working principle and characteristics are embodied in conveying high viscosity, high temperature, and highly corrosive materials. Its conveying process is smooth and continuous, and it can ensure that the physical properties of the materials are not broken during the conveying process, and the viscosity of the conveyable materials can be up to 1,000,000 CP.
